COMING OF AGE: Christos Garkinos and Cameron Silver, co-owners of Los Angeles designer consignment store Decadestwo, hosted a party last Wednesday night to celebrate the boutique's recent expansion, followed by cocktails at Social Hollywood that drew the likes of Garcelle Beauvais, Alyson Hannigan and Joely Richardson. China Chow, dressed in a vintage black lace Lanvin dress, couldn't resist perusing the store's new inventory, which includes a rack of Tom Ford-era Gucci pieces. "When I come into the store, I act like I work here," she joked. "I'm in the back rifling through things, telling them to take things off of eBay."

Ali Larter, clad in a Balenciaga jacket and vintage Levi's, shared Chow's enthusiasm for the store. "I'm always here," she said. "I pop in on random Tuesdays at 10 o'clock when I need something yummy."

Jared Leto dropped by to lend support to his mother, Constance Leto, whose jewelry line, Linda + Constance, was on display. Leaning over the glass case of baubles, Leto pointed to a small cluster. "Look at this nice little pile of sold things," he said with pride.

Silver, who recently returned from consulting stints in Europe for companies including Pringle and Samsonite, said, "It feels like we're really grown-up now. Combined, Decades and Decadestwo are 18 years old — we're finally legal!"

SHOW TIME: Commuun, the rising eco-oriented, Paris-based brand designed by Japanese duo Kaito Hori and Iku Furudate, will be staging its first show this October. The brand recently scooped up two Andam awards from LVMH Moet Hennessy Louis Vuitton and Longchamp that will help finance the show. "The collection will be much lighter with lots of transparency," commented Hori. Since starting out in 2006, Commuun has sold its clothes in stores such as Corso Como 10 in Italy and Dover Street Market. New accounts tapped since the launch of the brand's first pre-collection for spring 2008 include L'Eclaireur in Paris and Bergdorf Goodman and Saks Fifth Avenue in New York.
